/ilo'orriiigg now io the, forni olf Wire fabric illnstrziod in Figs. 'lto inclusive of the (lrmvinajis t-l'io reference, character l indicates'the longitudinal links, iolilink being made *2 boing forn'iell adjaformeye-portions 5 disposed to extend in a plane at right angles to thegeneral plane of the link-body.

The reference character 6 indicates the main-body of the lateral links,each lateral link having at each end a downwardly eX- tending arm 7projecting substantially at right angles to said main body 6. Formed atthe juncture of said main body 6 and its arms 7 are upwardly extendingrounded corner projections or U-shaped loops 8, the same providing seatsfor the eye-portions 5 of said longitudinal links when said laterallinks are threaded therethrough in assembling the respective types oflinks together to produce the Complete fabric. The free ends of each arm7 of the lateral link are turned or bent back upon themselves to formeye-portions 9 disposed to extend in a plane at right angles to thegeneral plane of the lateral link-bodies.

The longitudinal links, formed as above described are arranged inlateral rows, with their eye-portions 5 in lateral alinement. When thusarranged the lateral links are assembled therewith, by threading alateral link through the eye-portions of adjacent arms 2 of a pair ofadjoining longitudinal links so that said lateral linkl extends betweenand interconnects one of the arms 2 of one longitudinal link with an arm2 of an adjoining longitudinal link throughout the width of the fabric.When thus assembled the eye-portions 5 seat themselves in the respectivecorner projections or U-shaped loops 8 of the lateral links. As thusconnected with the longitudinal links, the lateral links are so disposedwith relation one to the other, that an arm 7 of one laterallink isbrought in close proximity to and in alinement with an arm 7 of theadjoining lateral link, so that the res ective eyeportions 9 of theadjoining arms?? are alined together and registered one with the other.

The 'next row of longitudinal links is now assembled and connected withthe lateral vthe registered pair of eye-portions 9 seat themselves inthe ring-shaped loop 4 at the f upper or doubled end of saidlongitudinal links. Thus the alternate rows of interconnectedlongitudinal and lateral links are built up or connected one with theother until the desired length of wire fabric has been completed. Tofinish oil' the longitudinal edges of the fabric thus produced theeye-portion 5 of the outer arm 2 of the outside longitudinal row oflongitudinal links is connected with the ring-shaped loop of thelongitudinal link next below the same by means of an interconnectingshort link le having an v`eye-portion 11 at each end for engaging theabove mentioned portions of the longitudinally adjoining longitudinallinks. lt will thus be seen that when the respective rows oflongitudinal and lateral links are assembled together in the mannerabove described, the former are in longitudinal alinement as well aslateral aline- Inent, and all longitudinal strains upon the fabric arein the nature of a direct pull or strain, end to end, from onelongitudinal link to another, as transmitted through the interconnectinglateral links, and the latter not only serve to interconnect thelongitudinal links so as to provide for a high degree of flexibilitybetween the interconnected longitudinal links, but also serve as lateralstretchers between adjoining longitudinal links, whereby while thelateral flexibility of the wire fabric is retained in an eilicientdegree, the longitudinal links are, nevertheless, maintained spacedapart and separated laterally one from another, so that the mow ingtogether of longitudinal links toward one another, and a consequentuneven distribution of the strains throughout the area of the wirefabric formed thereby, is pre vented, and a smooth iexible supportingsurface for the lnattress is maintained. The ends of the fabric thusformed are connected by the usual helical springs 12 with the supportingframe-work of the bed or springsframe.

ln order to stiiien the longitudinal edges of the wire fabric thusformed,` l provide a metallic band or strip 13, preferably of steel,which is interwoven with the lateral links between the 'two outerlongitudinal rows of longitudinal links. The ends of the sti'l'eningband or strip 13 are perforated as at 14, and helical-springs l5 connectsaid strip or band with the supporting frame-work of the bed orsprings-frame. This arrange ment is novel and useful in that the stripor band is directly inter-connected or interwoven with the longitudinaledges of the wire fabric, and is maintained in the plane ofv said wirefabric in conformity with all the iexing movements of the latter byreason of such close interrelation of the same therewith.

Referring now to Figs. 5, G and 7 of the drawings I have illustrated aslightly modified form of'wire fabric, still embodying, however, theprinciples of the present invention. In this construction thelongitudinal links are modified slightly so that the same While arrangedin horizontal rows are so disposed, when intereomueted by the laterallinks, that the. loiigitudiual links of one row are in staggeredrelation to the longitudinal links of the adioining lateral rows. Toaccomplish this end l employ a modified form ofv longitudinal linklcomprising a length of wire doubled upon itself to form a pair oflongitudinally extending arms 16.

el (l The upperportions of said. arms i6 :iro ini-.lined toward nachother, thus providing inwardly inclined portions 17 converging; towardthe connected ends or doubled over portion of the link-bodyo Theoonnectod 0nd or doubled ovor portion oli the link body is bowed orlient to form :i practically Closed ring-shaped loop i8 at one and oi'the linlpbofly.
